This paper presents a brief overview of high-speed vision systems that enable real-time image acquisition and visual processing at frame rates of several hundreds to thousands of frames per second, which are substantially higher than the standard video rates. High-speed vision systems enable fast measurement and control of dynamic systems, and have been successfully applied in the fields such as robotics, in which real-time perception of dynamic environment is critically important.
